From Teltonika:
We would like to inform you that from January 1st, 2025, part of our legacy devices (From current reports mainly: FM11YX, FM12XX, FM53, FM4) stopped detecting satellites (GNSS loss ) which resulted in sending the same coordinates (or 0,0) to our client servers. We have encountered similar GPS rollover issue in early 2019. The patch on the latest base firmware versions is already available and potentially most of the customers who use the above products have upgraded to firmware that has the patch. However, there will be a part of customers who have not upgraded to the firmware, or are using specs that have not been upgraded.
AFFECTED DEVICES:
FM10 series
FM11 series
FM12 series
FM4 series
FM53 series
FMA series
